I too support the Brotherhood of Steel fully. I was prepared to kick out the NCR because my friends said there could be no peace between NCR and the Brotherhood, but I found the way (despite self-imposed 10 points in speech, heh).
To be honest, the entire Brotherhood-NCR conflict seems a bit uncharacteristic of the Brotherhood. In-game they have only been secretive and protective, never aggressive. Even freely trading non-combat technologies to help humanity regenerate. I blame the conflict on Elijah.
(Though, Dead Money is the one DLC I haven't played yet. Ironic, since I was obsessed with finding him... I didn't know his role in that one until I completed the rest, and my friends told me while laughing).
As far as I'm concerned, they're the greatest (lawful) good left in the world. Certain military technology *should* be withheld, because the world is a savage place for now. All other technologies they collect, collate, and share. They represent the greatest ideals of the pre-war military merged with the pre-war scientific community. Warhammer space marines, they ain't.
The Followers of the Apocalypse may win in sheer generosity, but they fail in vision and effectiveness. But in my head-canon, the NCR adopts the Brotherhood and the Followers as semi-autonomous branches of government. With the NCR's scope, the Brotherhood's knowledge, and the Followers' humanitarianism, a truly good republic can emerge.
The only objectively good faction in New Vegas are the Kings.
I almost killed those punks until I learned the truth. Then I was happy to support them.
They're still kinda pathetic but whatever, every kingdom needs a county.
